as C. caerulesoens, and Zetterstedt, in 1855 (Dipt. Skan., xii, 4715), fully described 

 it as a separate species, Cyrtoneura picta, professing to recognize some other slight 

 differences, such as whiter alulse, narrower frontal triangle, less oblique transverse 

 vein, &c. He had apparently then seen several specimens from Sweden and Lapland. 

 I believe there is no notice of its having occurred elsewhere, and, though I consider! 

 the specimen of extreme interest, I must still hold doubts of its specific rank. 



(9) Calliphora groenlandica, Zett. — The common oblong, somewhat flattened, 

 dark blue Musca, common in London, and apparently occurring all over England and 

 Scotland, existing in English collections sometimes as M. eqitestris, sometimes M. ; 

 illustris, and sometimes M. azurea, is, I believe, Zetterstedt's C. groenlandica, as the I 

 palpi are yellowish, and the thorax and abdomen all of one colour in both sexes. 



(10). Morellia curvipes, Mcq.— All (4 6*) belong to a small var. I find this 

 species common in numerous localities.

NOTES ON BKITISH TORTRICES. 



BY C. G. EAEBETT. 



{continued from Vol. xvii, p. 267). 



In this Magazine for 1869 (vol. vi, p. 113), I recorded the curious 

 habit of a larva which I had found feeding in berries of JRhamnus - 

 frangula at Haslemere, and, when full-fed, forming a case out of a 

 piece of the leaf, in which to pass the winter, and stated my reason 

 for believiug it to be that of JEupcecilia ambiguella. 



As far as I know, this observation remained for more than ten 

 years unchallenged and unconfirmed, so it will not be difficult to 

 imagine the pleasure with which I received, in the summer of 1880, a 

 letter from my energetic friend, Mr. \V. H. B. Fletcher, in which hej 

 wrote : "I came down to the New Forest for a week in March, andJ 

 when searching for cases of Coleopliora ahenella on the Mhamnus franM 

 gula stems, I found some queer bottle-shaped cases on the stemsJ 

 formed of a piece of dead oak-leaf or bracken-frond. Towards the end ' 

 of April, a fine ambiguella came out indoors. It seems a queer idea 

 that the larva should feed on JRIiamnus, then take the trouble to go to 

 the ground to make a case of oak or fern, and then return to the stems : 

 to hibernate and pupate." 



This was gratifying, and I begged Mr. Fletcher to search for I 

 larvae in the berries, in the summer. This he did, and sent me a grand I 

 supply of berries containing scores of larvae. These larvse were slug- I 

 gish and plump, thickest in the middle, with slightly swollen segments.
